Media Access Control (CSMA/CD+ACK)
- CSMA/CA
- CSMA with Collision Avoidance
- Tries to avoid collisions
- When line is clear, station may send (CSMA),
- but before it sends, must wait a random amount of time
- This prevents stations that have been waiting to transmit from all transmitting at once when the currently transmitting station is finished
